"Oh!" Hunter says, starting in surprise at Pyrus's request. "Well, uh, we put some firewood into that can," he says, pointing at the flame-spewing can in front of him. "We're, uh," he scrunches his eyes in an attempt to remember Pyrus's lesson earlier. Then his face lights up in recollection. "We're burning away everything except the carbon!" he says. "That's what the flames coming out of the paint can are. It's the wood gas burning away. Pyrus says it's powerful enough to run a car at 85% efficiency," Hunter declares, proud that he remembered that little fact. "Once everything else burns away, what's left is charcoal, which we can use to make pretty much anything in existence!" Hunter beams at Willa excitedly. "Pyrus says we're gonna make gunpowder with it today."
